Abstract
Abstract A spray cleaner composition for use with a propellant that is gaseous at room temperature, for the spot treatment of textiles before washing, consisting essentially of, without propellant, (a) from 6% to 16% by weight of ethoxylated C 6 -C 10 -alcohols selected from the group consisting of alkanols and alkenols, having an average of from 4 to 8 ethylene glycol ether groups, wherein the content of saturated C 8 -alkanol is at least 50% by weight, (b) from 6% to 10% by weight ethoxylated C 12 -C 18 -alcohols selected from the group consisting of alkanols and alkenols, having an average of from 2 to 4 ethylene glycol ether groups, wherein the content of C 16 -C 18 -alkanols is not more than 50% by weight, (c) from 6% to 10% by weight of ethoxylated of C 16 -C 18 -alcohols selected from the group consisting of alkanols and alkenols, having an average of from 10 to 15 ethylene glycol ether groups, (d) from 20% to 50% by weight of aliphatic hydrocarbons having a boiling range of from 180° to 260° C., and (e) from 10% to 35% by weight of at least one chlorohydrocarbon selected from the group consisting of methylene chloride, ethylene chloride, 1,1,1-trichloroethane and perchloroethane; with the proviso that components (a), (b) and (c) amount to from 20% to 35% by weight of said composition and components (d) and (e) amount to from 65% to 80% by weight of said composition.
